BUTTON-MAKING MACHINE'.

Zen'softhe UnitedStates?,I residing at New usefullv mprovements inButtonllllaking'Maf l chilies',v of which the following isfa' specifi-IThis invention comprehends certain new and -fuseful improvementsmachines i for making buttons," and the invention vhas for its ljirima-ry objecta button forming in aohine' which g will practicallyautomatic inail of the' operationsofv facing, grinding,

drilling and 'the other operations ofv transy forming buttonblankslintol the completed articles. i 'A y l'The' invention 'alsofhasfor its object a machine of Athis character embodying a rrevoluble drumvor chucklcarrying table and a plurality of sets oflfacing and' drillingtools carried there y; thepaifts being. so constructed anfdE arrangedthatl =the blanks will berec'e'iijed'in the machine from a feedingdevice anr'l'be'ct'rried around in the machine and faced andldrilledfoneafter Athe other so as to produce a practically co'ntinu'ousoper`-ation,l the 'completed' buttons being finally and preferablyautomaticallyVA discharged from the machine preferably at about the samepoint that the blanks are fedY into the machine.

Theinvention also hasfor one of its primary objects a button: formingmachine an. plicable for' use in forming hsh'eye but-v tons7 as well' asbuttons of other types, the machine being Icapable of'ouick and easy`'adjustment of parts, whereby the blanks may be first Afaced and thendrilled so that four thread receiving holes are formed; or, if desired,first faced, then formed with a fish eye, and then immediately or subsefluently forniedwith two thread receiving holes,- in the continuousoperation of the machine.

The invention has for a further object a machine of this type embodyinga. plurality of toolV holders each of which carries facingtool and a'drill. said tool holders being automatically movable in a radialdirection as they are carried around in the reveluble movement of thechuck supportving table, "whereby the blanks may be first `frspeim mi nof Leiters Patent.

faced and subsequently, by this radial move?` ment' ofthetool holder,have thebits drills'b'ro'u'ght .into vertical alinement with the blanks,Awhereby the' automatic upward` movement'o'f thechuck will causeitheblank Q to be. carried against thel drill andthe holes formed intheblank.`v i

A lstill`=further object of the invention is a buttonfformingmachinefwhichfwill include simple and eflicientfme'ans for auto'matically rotating the chucks during the face forming operation,automatic means for locking the chucks one after the other, so astoprevent theirl rotation immediately after the face-*forming operationhas beer'icompleted, andf'autoinaticmeans for inter,- mittinglyimparting partial rotations to the chucks, between' which rotationslthe' chucks arelooked, ywhereby the blanks may be given either quarterAor half turns as one'Y hole after the other is "drilled, according towhether four or two holes areto be formed intheblanks. i

Thel invention also lhas for its object a machine of this "characterwherein the facing tools are ground and kept sharp in the continuousoperation yof, the machine without the necessity of Vstopping the same,

and wherein slight 'downwardI movements.'

arel imparted by' automatic'meansto the facing tools after predeterminedintervals, so .as .to compensate for'v the 'worn edge thereof'.

A further v'object of the invention is a but- I ton forming lmachine inwhich all dust particles or grindings from the shellsv will beeffectively disposed of in the continuous operation'oflthe machine,thereby notonly tending to maintain hygienic conditions for theoperators, but toalso protectfthe bearings of the operating elements ofthe apparatus.

A further object of the invention is a button forming machine includinga novel fish eye forming mechanism wherein the fish eye tool ismountedi'for oscillation through a predetermined arc of the circle inwhich the series of chucks revolve, the parts being so arranged thatwhena blank reaches the fish eye tool and .is raised to operative`engagement therewith, ythe rapidly rotating tool will be carried alongat the same speed with the chuck until the fish eye has been formed, andwill then be automaticalily released? and quickly- 'retjurnedto itsinitial-positionready for opera-tion upon the next blank in the series.

The invention also aims to produce amachine of this generalcharacterwhich can be4v easily adjusted so as to give either quarter or halfturns to the blanks in the drilhngf operation, according to the numberof thieaiireeeivifngholes it' desired* to' formi therein. u 'l u Theinvention also aims to produce a but ton formingmachine providedwithabend in or, attachment gwhichds: so arrangedthat it can form amilled vedge 1n the blank, the same be desired,this 'attaclif menthemgcapable ofready ldisc'onnection ,when not. desired for use- Theinvention also produce a but` ton forming: machine which is capable eladustnlent- Aso' as toreadily and .automatically form buttons ofthethree-quarter bore F type, ,as will' be hereinafter more fullydescribed. the invention also aims to work, and
